Currently I have backbottle phantom, and i love it. Sometimes i feel it's too long, so I thinking about bottom line, and it makes it seats closer to me so i can aim much easier. I have guerrilla air 13ci hpa tank Here the questions
1. are they comfortable?
2. comfortable for snapshooting at both arms (right and left)
3. does it make phantom anymore heavier?
4. does it increase or decrease the accurary?
